摘要:
A lithographic apparatus is disclosed that has an imprint template and a substrate table configured to hold a substrate, the imprint template having a patterned surface, a layer of heat absorbing material provided on the patterned surface of the imprint template.

A lithographic apparatus is disclosed that has a template holder configured to hold an imprint template, a substrate table arranged to receive a substrate, a radiation output arranged to illuminate a part of the imprint template, and a detector configured to detect radiation scattered from an interface between the imprint template and imprintable material provided on the substrate.
摘要:
An imprinting method is disclosed that involves, in an embodiment, redistributing a volume of imprintable medium in a flowable state over a target portion of a surface of a substrate into regions of differing volume corresponding to regions of differing pattern density of an imprint pattern of a template, contacting the medium while in the flowable state with the template to form the imprint pattern in the medium, subjecting the medium to conditions to change the medium into a substantially non-flowable state, and separating the template from the medium while in the substantially non-flowable state.
摘要:
An imprinting method is disclosed, in which an embodiment involves subjecting an imprintable medium on a substrate to conditions such that the medium is at a first temperature so that it is in a flowable state, the imprintable medium comprising an imprint material selected from a group consisting of: a crystalline material and a polycrystalline material, pressing a template into the medium to form an imprint in the medium, cooling the medium to a second temperature such that the medium is in a substantially non-flowable state while the medium is contacted by the template, and separating the template from the medium while in the substantially non-flowable state.
摘要:
A device manufacturing method is disclosed. The method includes patterning a beam of radiation with a patterning device, projecting the patterned beam of radiation onto a target portion of a substrate, supplying a chemical reagent to a chamber that holds the patterning device and/or the substrate, and removing water from the chamber with use of the chemical reagent.
摘要:
Liquid is supplied to a space between a projection system of a lithographic apparatus and a substrate, but there is a space between the liquid and the substrate. An evanescent field may be formed between the liquid and the substrate allowing some photons to expose the substrate. Due to the refractive index of the liquid, the resolution of the system may be improved and liquid on the substrate may be avoided.
摘要:
An ultrasound transducer is configured to be driven at multiple frequencies including a main frequency for efficient production of ultrasound waves and at least one alternative frequency, at which little or no ultrasound is generated and rather heat is generated in the ultrasound transducer for heating a sample.
摘要:
In a lithographic projection apparatus, a structure surrounds a space between the projection system and a substrate table of the lithographic projection apparatus. A gas seal is formed between said structure and the surface of said substrate to contain liquid in the space.

摘要:
A lithographic projection apparatus is disclosed in which a space between the projection system and the substrate is filled with a liquid. An edge seal member at least partly surrounds the substrate or other object on a substrate table to prevent liquid loss when edge portions of the substrate or other object are, for example, imaged or illuminated.
